Oswego, NY -- A report of a suicidal man with a gun inside a home near Kingsford Park Elementary School forced Oswego City School District officials to lock the school down Monday afternoon, police said.

Someone called the Oswego County 911 Center at 3:08 p.m. to say the suicidal man had a gun at 258 W. Third St., Oswego, city police Capt. David Lizotte said in a news release. The man was alone in the house and he was not a threat to anyone outside the area, Lizotte said in the release.

Kingsford Park Elementary was put on lockdown as a precaution, police said. The school is back open now.

"At no time were students in danger," Lizotte said.

Oswego city police and Oswego County sheriff's crisis negotiators called the man, who walked out of the house voluntarily at 4:23 p.m., Lizotte wrote in the release. The man has been taken into custody.

Police said they have not recovered a weapon, but the investigation is continuing.
